In his first-ever interview, the sole Australian survivor of the Waco siege has revealed to 60 Minutes what really took place during the 51-day stand-off, and why he believes crazed cult leader David Koresh will one day return to Earth as the son of God.

The Telegraph newspaper reports that she is highly regarded in her field, having been awarded an Order of the British Empire in 1997 for her services to earth science.

After her bleak cancer news, Professor Plant learned that while Chinese women had historically very low rates of breast cancer, the rates were more in line with western countries when Chinese women moved to places like Britain or Australia and adopted western diets.

Her husband recalled that his Chinese colleagues would give him powdered milk because they did not drink it themselves.

So the mother-of-two, who had already cut down on animal protein such as meat and eggs, tried switching to a dairy-free diet while undergoing chemotherapy.

Within 12 months she was in remission.

Professor Plant first published her story in the book Your Life in Your Hands, which many cancer patients claimed helped them to recover.

But three years ago she became lax about her diet and her cancer returned.

Once she returned to her strict diet as well as starting to walk regularly, meditate and take an oestrogen suppressor prescribed by her oncologist, Professor Plant was in remission again after just a few months.

Her new book, Beat Cancer, advocates eating more plant foods and less red meat, sugar, salt and fat, as well as regular exercise and reducing stress levels.

Her main claim is that dairy products should be totally excluded from any diet to deny cancer cells the conditions they need to grow and spread.

Her approach to cancer reportedly is supported by some eminent scientists.

Her latest book, co-written with Mustafa Djamgoz, professor of cancer biology at Imperial College, has a foreword from Professor Sir Graeme Catto, president of the British charity College of Medicine, who describes its findings as "illuminating … even, at times, shocking" but all backed up by scientific research.
